In the past ten years, the country has actively advocated the development of energy-saving buildings and reduced energy consumption, which has made the external insulation technology of expanded polystyrene board thin plastering external wall widely used. The demand for molded polystyrene foam plastic for thermal insulation (hereinafter referred to as EPS) is increasing, which has driven the rapid development of EPS production enterprises. Polystyrene foam plastic is made of polystyrene resin as the main body, adding foaming agent and other additives. It is a kind of buffer material that is widely used at present.

In recent years, five national supervision and spot checks have been carried out on molded polystyrene foam for thermal insulation, and the product qualification rates are 95.1%, 96.3%, 97.5%, 97.5% and 97.8% respectively. The product quality is steadily improving, but there are still certain problems. The main issues focus on apparent density, oxygen index, combustion classification, etc.

When the density of polystyrene foam plastic board is insufficient, if it is used for external insulation of building exterior wall, its tensile strength will be low, which can not meet the bearing requirements of the self weight of the insulation system and the finishing load on its shear strength, and it is easy to break the middle of the EPS board; At the same time, the insufficient density of EPS board will also lead to the reduction of thermal insulation performance and increase of moisture absorption, which will affect the thermal insulation effect of buildings. Polystyrene foam board will not play a role in building energy conservation and thermal insulation.

At present, there are about 2000 manufacturing enterprises in China, and the production of polystyrene foam plastics has a good momentum and the quality continues to improve. However, the number of large enterprises is relatively small. It is reported that the apparent density refers to the mass of foam plastic per unit volume under the specified temperature and relative humidity conditions. The apparent density affects other physical performance indicators to a certain extent and directly reflects the cost of the product.

Manufacturer of foam boxThe produced foam boxes and EPS packaging products are widely used in the packaging of household appliances, power tools, instruments, LCD displays, aquatic seafood, edible fungi, fruits and vegetables, vaccine reagents, hardware lighting, handicrafts, glass, ceramics, and exported furniture products, with good cushioning, anti-collision, heat preservation and cold storage effects. In the future, the company sincerely hopes to cooperate with powerful and reputable electrical appliance production enterprises, printing and packaging enterprises, real estate developers and contractorsInsulation boxWholesalers and friends from all walks of life who are committed to packaging and energy-saving insulation work together to create a future and make new contributions to the country's energy-saving insulation industry.
